Home choice online shopping pathetic

Shocking online portal Advertised something on special Showed in stock. Placed order which included the R200.00 delivery fee. Payment made using their online portal and went off my account successfully. There was no option for me to change amount and the amount they quoted was debited. I received an email saying thank you for order and payment and would get sms about delivery when ready. The very next day my order status is R2000 more and showing as awaiting payment! I email call centre, no response, so I call the following day only to be told item not in stock, my payment not showing, there is a +R1000 something charge for shipping and another charge for assembly and al these additional fees and amounts not reflecting online or in the sale process Customer service agent had no clue what was what and kept giving different reasonings, all which made no sense and not part of the buying online process. And worst of all while I’m complaining and asking what is going, the call centre agent puts me on hold and never returns back to call. So wasting more of my time and money. Surely when you reach the step of “complete payment” on an online transaction those are the costs agreed upon. Reason you rush to buy sale items is for the discount, they can’t tell you the day after oh sorry no sale when it was advertised when you paid for it. Absolute joke! No wonder they harass and call people on their cell phones constantly. ****************! Absolutely worst online shopping I have ever experienced!!!!
